Work Piece Material | Hardness | V(m/min) | f (mm/rev) | Ap (mm) |
Gray Cast Iron | HB170~300 | 500~1500 | 0.1~0.4 | 0.1~1.5 |
Alloyed Iron | HB240~300 | 150~300 | 0.05~0.4 | 0.1~0.5 |
Nodular Cast Iron | 100~350 | 200~400 | 0.1~0.4 | 0.1~0.5 |
P/M Fe-based | HRC55-65 | 50~150 | 0.05~0.4 | 0.05~0.5 |
Hardened Steel | HRC55~65 | 80~200 | 0.05~0.2 | 0.05~0.2 |
Heat-resistant Alloys | 110~160 | 50~200 | 0.05~0.2 | 0.05~0.2 |
1. Hardness up to 8000 HV , is 80 ~ 120 times to hard alloy
2. Coefficient of thermal conductivity is 700 W/mK, 1.5 ~ 9 times to hard alloy
3. The friction coefficient is commonly 0.1 ~ 0.3 , It can significantly reduce the cutting force
4. Thermal expansion coefficient of just 0.9? 10 ^-6 ~ 1.18? 10 ^-6. So the tool thermal deformation is small and the precision is high during processing .
